Extra Mario Bros; a Skin Set

So I was thinking of constructing a map skin based around the quite well-known SMB1 ROM hack Extra Mario Bros, a hack that plays very similarly to Metroid with it's very non-linear gameplay style and upgrades system.

Some time ago I ripped nearly every tile from EMB for the Mari0 community and had since then also ripped the ? blocks and extracted the enemy graphics via YY-CHR.

I was considering making this into a skin for SMBC, and if I do go through with it, it'd be my first major skin contribution (aside from SMBS PC-88).
